Project
Capstone Design: Electromagnetic Bicycle Damper
Fall 2025 - Spring 2026 • School Project
Engineered the electromagnetic hardware and active control system for a dynamic, real-time magnetorheological (MR) fluid mountain bike suspension damper.
Skills Used
MATLAB Python Jupyter Arduino
Details
- Designed and validated an internal electromagnetic coil for an actively controlled magnetorheological (MR) fluid mountain bike damper, utilizing a 26-AWG copper coil and steel core operating at 10W and 2A to generate an estimated peak 0.15 Tesla magnetic field across a 2.5 mm radial gap
- Modeled magnetic field strength and spatial geometry using the Biot-Savart law and complete elliptic integrals in Python, ensuring field lines oriented perpendicularly to fluid flow to maximize yield stress activation
